I have a lovely 1100s the previous owner kept it absolutely spotless - however it seems to be developing a bit of a weird problem. At speeds of over 70 it seems reluctant to turn right? Left turns are fine but sweeping right handlers it just feels horrible. Could it be the tyres being squared off? Could it be head bearings or steering damper? Is it a by product of the flat twin torque reaction? I’ve started to wonder if it’s me losing my sense of balance but I don’t think I am..

has the final drive / drive shaft / paralever been removed recent for service of some kind (pivot bearings?)the drive shaft UJ's have to be phased / orientated correctly other wise this type of feeling can occur.I experienced kit similar to as you describe when i first did the final drive pivot bearings on my 1150GS.

It can be tricky to do!IF the final drive has been removed and re-installed lat

This is how I suggest to resolve:-Remove final drivePut the gear box in gear, by hand turn the drive shaft that is in the paralever until it can turn no more (slack is taken up, its normal)with a good light, look up the paralever and see the clock angle of the forward Universal Joint (UJ)You need to get the Final drive splines mated so that the final drive UJ is the same as the forward one.Now, stuff MOST of a rag in to the paralever to partly support the drive shaftOffer up the final drive and feed the final drive UJ Spine in to the drive shaftinstall pivot pinsREMOVE THE RAG!re-install the rubber boots reinstall torque linkcheck work

When I have fully dissassembled the paralever and drive shaft, I have checked them on a bench for alignment and painted strips along the entire lenght to aid and assist alignement later.

I did find that doing it on a bench was close alignment, and then I looked again and rotated the final drive almost 180degrees it was even closer! (doing this pretty much requires the entire paralever removal - I dont think its a big job, but knoweldge, tooling and facility will dictate that)

Just the way it is. If the ball joint fails it is usually due to wear on one side - hence making the bike difficult to steer and pulling When you see a ball joint removed you can see that if its failed its stiff and does not rotate freely through 360 degrees, whereas a working one does move freely through 360 degrees

Could it be it's normally parked with the wheel locked to the same side hence it could corrode unevenly? Or because the bike leans humidity would be more likely to be trapped towards the left, then corroding or ruining the greasing?

My bike seems to have a harmonic type of vibration feel when I'm riding.

Its always been there from when I bought it a few years ago .Recently the rear wheel bearing failed , and I guessed this may have been the cause .But the vrrr vrrr type feeling is still there when I ride .

I'm now wondering if the drive shaft is out of synch and that is causing this odd feeling when riding .
